SPECIFICATION forming part of Letters Patent No. 728,78 6, dated May 19, 1903. Application filed January 17,1903. Serial No. 139,420. (No model-l T0 all 1071/0772, t may concern.-

Be it known that l, EDWARD VILLENEUVE, a citizen of the United States, and Va resident of Salem, in the county of Essex and State of.

This invention relates to improvements inV an upper-guard for heel-trimming machines, and it is especially well adapted for use on that class of such machines termed springheel trimmersg andit has foritsobject means for preventing the rotary cutter from cutting too deep in the curved contour of the heel, for which purpose I employ, in combination with the rotary cutter and its shield, an adjustable upper-guard against which the upper is guided during the trimming operation, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Fignre l is a top plan View ofthe invention, parts being shown in section. Fig. 2 is a longitudinal section on the line 2 2 shown in Fig. 1, and Fig. 3 is a bottom plan View of the improved guard.

Similar letters refer to similar parts Whereever they occur on the different parts of the drawings.

In the drawings., A represents a portion of the head of a spring-heel trimmer of any Well-known construction, and B represents a stationary part of the frame, as usual.

C is the heel-rest, against which theV` top lift of the heel to be trimmed is held during the trimming operation, as usual.

D represents a portion of the rotary trimmer-shaft, which is capable of longitudinal movement according tothe height of the heel that is being trimmed.

E is the rotary cutter, secured to the shaft D, and' F is the shield, secured to the outer end of the cutter, as usual.

G is the improved guard, having at its rear end a slot g, in which is longitudinally adj ustable a block H, preferably provided with a slotted aperture h, adapted to receive the correspondingly-shaped end 7l of the bolt or post I, which latter is secured to the frame portion B or other suitable part of the machine. The outer end of the bolt portion 't' is screw-threaded and provided with fastening-nuts K K', by means ot' which the block H may be firmly secured `to the bolt I.

.the outer end of the guard G and having its inner end universally connected to the block H, as shown in Figs'. land 2, so as to permit the guard .G to oscillate vin a horizontal direction relative toY Vthe block H during the Alongitudinal movement of the cutter E and its shield F. In practice the adjusting-screw L is connected by means of a ball-and-socket joint to the blockll; but it may be otherwise connected by similar mechanism without departing from the essence of my invention.

M is a spring interposed between the guard G and the frame portion B, and it serves for the purpose of holding the free end of the girardin contact with the shield F during the longitudinal motion of the latter, as shown.

In dotted lines in Fig. l, N represents the heel of the boot or'shoe to be trimmed, O is the rand, and P represents the upper, as usual. P, in dotted lines in Fig. 2, also represents a portion of the boot or shoe upper.

In one piece with or pivotallyconnected to 'the inner end of the guard G is an upper guide or nose G', which in practice I prefer to pivot at g' to the inner end of the guard G, and said upper-guide is normally held in the position shown in the drawings by the inlluence of a suitable spring g1?, secured to the guard G and adapted to bear against the `guide G', as shown in Fig. 2.

During the operation of trimming the heel ,of the hoot or shoe the top lift of the heel is held against the stationary heel-rest C, as usual. The contour of the heel to be trimmed is held and adjusted by the operator with proper pressure against the rotary cutter and the shield F inserted in the rand at the junction of the heel and upper, as is usual in the art of trimming heels. During such operation the upper portion of the boot or shoe is caused to bear against the upper-guide G', thus preventing the rotary cutter from cutting too deep on the curvature ofthe heel and causing the contour of the heel to be cut parallel with and concentric relative to the contour of the upper. By having the nose G' yieldingly connected to the guard G it is capable of yielding upward when passing by L is anadjusting-screw screwed through 1 IOO ' and claim is- 1. In an upper-guard for heel-trimming,r machines,the combination with astationary sup.- port, a cutter, and a cutter-shield, of a bar longitudinally adjustable upon and pivotally connected to said support, and provided at' its free end with a yielding guard-nose, and a spring arranged to hold the side of the free end of said bar in contact with the cuttershield, substantially as described.

2. An upper guard for heel-trirninirrsr niachines,the combination with astationary su pport, a cutter, and` a cutter-shield, of a bar longitudinally adjustable upon and pivotally connected to said support, a yieldinl,r guardnose pivotally connected to the free end of said bar, aspring arranged to yieldingly hold said guard-nose against a shoe in contact with the cutter-shield, substantially as described.

In an upper-guard forheel-trirnming inachines,the combination with a stationarysnpport, a cutter, and a cutter-shield, of an oscillatory bar adjustably mounted upon said Y support, a yielding guard-nose pivotally connected tothe free end of said bar, and a spring arranged to hold the side of the free end of said bar in contact with the cutter-shield, substantially as described.

4. In an upper-guard for heel-trimmingr machines,tl\ecombinationwithastationarypost, a cutter, and a cutter-shield, of a bar longitudinally slotted at one end, a block adjustably fitted in said slot and pivotally mounted on said post, means for adjusting said block in said slot, a yielding guard-nose pivotally connected to the free end of said bar, and a spring arranged to hold the free end of said bar in Contact with the cutter-shield, substantially as described.

5. In an upper-guard forheel-trimming machines,tbe combination with astationary post, a cutter, and a cutter-shield, of a bar longitudinally slotted at one end, a block adjustably fitted in said slot, an adjusting-screw mounted in said end ot' the bar and swiveled at its end in said block, the said block being pivotally mounted on said post, a yielding guard-nose pivoially connected to the free end of the bar, a spring` arranged to hold said guardnose against the shoe-upper, and a spring arranged to hold the side'of the free end of the saidbar in contact with the cutter-shield, substantially as described.
